SimSwap: An Efficient Framework For High Fidelity Face Swapping

Proceedings of the 28th ACM International Conference on Multimedia

The official repository with Pytorch

Our method can realize arbitrary face swapping on images and videos with one single trained model.

Currently, only the test code is available. Training scripts are coming soon
